Along with Shiloh, Suri and Apple, here's a new celebrity baby name: Everly Bear.
Confirming rumors in the rock-and-roll world, Anthony Kiedis told PEOPLE on Saturday he is the father of a son, whose first name was musically inspired.
"We had a long list of names, but I suppose it came to me by way of the Everly Brothers, which is one of my favorite bands," the Red Hot Chili Peppers singer said at a fundraiser for the Sea Shepherd Conservation Society in LA. "And sometimes last names make good first names."
Kiedis's girlfriend Heather Christie came up with the rest. "The mama came up with Bear," Kiedis says. "That made sense to me because he's from me and I feel like I'm part of the bear clan, and I think it's nice to have a little bit of earth in your name."
Kiedis and Christie, a model, reportedly welcomed the new addition to their family on Oct. 2 in Los Angeles.
"Being a father is different, it's much different," Kiedis says. "I sleep when I can, but he's letting me off pretty easy so far. He's a very calm and peaceful kid."
